Allow no-change steps inside of Flows
In order to make a flow more versatile, it would be good if a 'edit' step within a flow could be navigated without editing. So, for example, if I have a flow that involves reviewing the data in a record; with the option to stop and change things at each step, the user might hit a step in the flow where they don't need to change anything, but still need to get to the next step in the flow. The 'Save' button should be accessible in these cases even without an edit.

typing a character in any field and deleting it will "dirty" the record and prompt the save. Just make sure in your flow that you have a decision in place in case nothing changes otherwise it will save the record, but end the flow because it doesn't know where to go.
